Application filed. April 9,

My present invention relates to improvements in cream separators of the siphon type, and especially kdesigned for use in connection with the standard type oi milk bottlcs, whereby the purchaser ofthe bott-le of milk may separate the cream therefrom by drawing the latterA 'from the milk and depositing the cream in a suitable receptacle 'irovided therefor. As is well known in domestic. circles itis desirable for many reasons and purposes to separate and draw ott the accumulated cream from the top of the mill: bottle as the latter is delivered by the milkman. Numerous devices have been design-ed for this purpose, but those with which I am acquainted have proven unsatistactory, as it has been found practically impossible to pour oit or draw ott the cream without at the same time mixing milk with the ere-ani as the separation takes place. By the utilization ot the device of my invention in connection with the bottle of milk, the cream may be drawn oit from the top of the bottle ot milk without disturbing the milk contained therein, and the cream deposited in a receptacle tor future use.

The invention consists, in certain novel combinations and arrangements ott parts involving the use ot a siphon as will hereinalter he more 'tully set forth and claimed.

lu the accompanying drawings I have illustrated one complete example of the physical embodiment ot my invention wherein the parts are combined and arranged in accord with the best mode I have thus tar devised tor the practical application of the 'principles of my invention.

Figure l is a view showing in side elevation a bottle ot milk with which my invention. is used, the draft tube being shown in operative position, with the bulb ot the .siphon device and the cream receptacle or glass-cup in section.

Figure 2 is an enlarged detail section ot the suction head connected with the draft tube.

Figure 3 is an enlarged, interior plan view ot the suction head with the dratt tube in cross section.

In order that the general relation and assembly of parts may readily be understood I have shown in Figure l a standard type ot milk bottle as 1 with the usual top annular rib 2, and the line of separation between 192. Serial NO. 100,902.

the accumulated cream and milk in the bottle is indicated in dotted lines.

rlhe cream from above the dotted line in Figure l is to be drawn by suction and deposited in the receptacle or glass cup 3, which is fashioned with an annular, flaring mouth 4t. The cream or other liquid is drawn .troni the milk bottle through the dratt tube 5 which may be fashioned of suitable material, pr vided with a goose-neck eend or return bend 8, and a shut oit valve 5 which controls the iiow oi' the liquid. The inlet or suction end ot the tube is formed with an outwardly 'flaring mouth 6 as best seen in Figure 2.

A pivoted suction head 7 is carried at the suction or inlet end ot the tube. said head being ot suitable material and ot coucavoconvex shape. A pair ot trunnions 8 extend radially trom the suction end ot the tube, and the suction-head 7 is provided with diametrically arranged perforated ears 9 by means of which the suction head is pivoted on the trunnions. The trunnions are preterably o'iZ wire and are termed with an intermediate attaching loop 10 which passes around and encircles the major portion ot the circumference of the lower end ot the dratt tube 6. In this manner the suction head is pivoted to or pivotally suspended at the lower end of the suction tube in order that the head may be turned to the (dotted position) angular position in Figure l and inserted in the erean'i without causing undue disturbance ot the cream. rlhe pivoted suction head is oi course ot such diameter as to permit its entrance into and exit from the mouth ot the milk bottle.

The suction head is inserted down through the cream until the under or convex surface ot the head reaches the line ot separation between the milk and cream, and the cream enters this suction head over the edge l1 which pass over the wall of the head and at the exterior ot the head open just above the line of separation.

In connection with the Siphon or draft tube I utilize a collapsible bulb 12 of the usual rubber type which has attaching heads 13 'for securing it at the lower or outlet end of the tube 5, and an annular series of air holes 14 are provided in the bulb.

In use the suction head is inserted in the upper end ot the milk bottle and the bulb ia placed in the upper open end of tbe reeeptaele 3, il' being umlerslood olf' course l'bal llie ref fepiaele is at a lower level than lille lower level olE ille cream line in ille milk bottle. The bulb is sealed in tbe outwardly llarineT lop edge ol ille reeeptaele l and is adapted lo forni a isabel-aniiall)v air liigrlli joinl lberen'il'li when tbe bulb i5 expanded, as iiuliealed.

Thilo located in il@l seal ille bulb is eoinpreseed lo loi-ee air lroin (he interior iberool, through l'lie receptacle, and lbenee out al the lop edge oil tbe receptacle. Compre5- aion is lben released 'from tbe bulb, the latter is sealed in the top flaring lnouli oli' the reeeptaele lo prevent ingrees of air `from the atmosphere, and the expandingl bulb causes air lo flow from the receptacle into the bulb tl'n'ougli holes ll, creating a partial Vaeiunn n the receptacle. The cream is memes tillen `forced by :,ltlnosplierie pressure from the bottle inlgo llie reeepl'nele in well known manner.
